OpenTelemetry and Jaeger | Key Features & Differences [2025]
OpenTelemetry is a broader, vendor-neutral framework for generating and collecting telemetry data (logs, metrics, traces), offering flexible backend integration. Jaeger, on the other hand, is focused on distributed tracing in microservices. Earlier Jaeger had its own SDKs based on OpenTracing APIs for instrumenting applications, but now Jaeger recommends using OpenTelemetry instrumentation and SDKs. Warning The original Jaeger client SDKs (based on OpenTracing) are archived and no longer maintained.
